SPECIFICATION forming part of Letters Patent No. 417,745, dated December24, 1889.

-Applicati0n filed June 27, 1889. Serial No. 315,775. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN M. SAILER, of Milton Junction, in the county ofRock and State of Wisconsin, have invented new and useful Improvementsin Grain-Separators; and I do hereby declare the following to be a full,clear, and exact description of said invention, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

The object of my invention is to provide a less expensive and moreenduring device for separating the straw from the grain in athrashing-machine than has been heretofore in use, which device isoperated with comparatively a-small amount of power, and by reason ofits peculiar operation is especially adapted for thoroughly beating thegrain from the straw and carrying the straw over the tail of themachine.

In the drawings, Figure 1 is a vertical longitudinal section of myimproved device, shown in connection with so much of a thrashing-machineas is necessary to indicate its relations thereto. Fig. 2 is a top viewor plan of my device, parts being broken away to' show other parts. ofmy device.

In the drawings, A is the case of the rear part of a thrashing-machine.

B is the toothed cylinder of the machine, and C is the beater.

Two upright arms D Done at each side of the machineare pivoted at theirlower ends on a rod E, supported in brackets F F, which brackets areaffixed to the case A of the machine conveniently to the uprights G G,which are a part of the case. At a distance above the rod E is across-bar H, inserted in and supported on the arms D D, on whichcross-bar H is supported one end of .the shoe I. The shoe I is hinged tothe cross-bar H, so as to permit a movement of the shoe thereon. Theshoe I extends forwardly to Fig. 3 is a rear end View and beneath theplace of the discharge of the straw and grain from the cylinder-concaveJ. At each side of the shoe, near its front end, there is secured to itslower surface a bracket K, having a central aperture adapted to receivetherein and fit movably upon the rotating bearing L, which bearings L Lare fixed eccentricaily on shaft. M, the shaft M having its bearings androtating in brackets N N, affixed to the case A and conveniently touprights 0 O of the case. The shaft M carries a band-wheel P, wherebymotion is communicated to the shaft. Two flexible straps R R-one at eachside of the machine-are secured at one end to a cross-bar H, inserted inthe arms D D, between the rod E and cross-bar H, and these straps R Rare carried forward to and around pulleys S S, journaled on the shoe I,near its front end, the straps running rearwardly therefrom above theshoe to a cross-bar H, secured in the upper extremities of the arms D D,at a distance above the cross-bar H, to which crossbar H the other endsof the straps R R are attached. Transverse slats T T, running from oneside of the machine to the other, are atlixed to the straps R R at alittle distance apart on their upper surfaces from the pulleys S S tothe cross-bar H.

The shoe I is provided with low upwardlyextending sides U U and a frontend board U, and its bottom is perforated at the rear part, forming ariddle V. It will be understood that the shoe I is reciprocated endwiseby the rotation of the shaft M, and that as the shoe is carried forwardfrom the position shown in Fig. 1 the arms D D will be tilted in thedirection shown by the dotted lines, and thereby the straps RR above theshoe will be considerably loosened, and will sag down into the positionshown in the dotted lines, only a small portion of the slack being takenup by the straps running over the pulleys S S to supply theslightly-additional length required in the straps below the shoe, onaccount of the greater endwise movement of the shoe than is given to thestraps below, and that as the reverse movement of the shoe carriesthearms D I) back again into the position shown in Fig. 1 the straps abovethe shoe will be thrown up quickly into the taut position shown in thatfigure; that as these motions are repeated rapidly the straw and grainthrown upon the separator and conveyor are thrown upward and rearwardlyby the movement of the straps and slats forming the separator andconveyer, and the grain is thereby separated from the straw and'fallsbetween the slats upon the shoe, and the straw is tossed intermittinglyto the rear and finally over the tail of the machine.

The foregoing description of my device has been entirely of the deviceas shown in Fig. 1, in which the cross-bar H" is located ata greaterdistance above the cross-bar II than the crossbar II is located belowthe crossbar 11, in which case the tilting of the arms D D gives aconsiderable amount of slack in the upper portion of the straps R R, ashere inbefore described; but as sometimes it is desirable to red ueethat slack to a minimum, or even to so adjust the straps that the partof them above the shoe will have no more movement than the part belowthe shoe with reference to each other, the cross-bars H and H areinserted adjustably inslots Dand D therefor in the arms D D, whereby theends of the straps R B may be adjusted nearer to or farther from thecross-bar II, as desired, in order to provide for greater or less sag inthe upper portion of the straps, as shall be desired.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a grain-separator, of upright swinging arms, ashoe hinged and supported at one'end on the arms centrally, and aseparator and conveyer consisting of flexible straps attached at theirends to the upright swinging arms respectively above and below the pointof attachment of the shoe to the arms and running forward to and aroundhearings on the shoe near its front end, and provided with transverseslats, with mechanism for reciprocating the shoe, substantially asdescribed.

2. In a grain separator, the combination, with upright arms D D, pivotedat their lower ends on the case, and flexible separator attached at oneend to the arms D D, near their pivotal point, and at the other end atconsiderable distance from the pivotal point, of a shoe I, hinged at oneend to the arms D D, between the points of attachment of the flexiblesepa rator thereto, and supported movably at its other end and providedwith bearings near its other extremity, about which bearings theflexible separator passes movably, with means for reciprocating theshoe, substantially as described.

3. The combination, with. the case of a grain-separator, of a shoe I,having rigid journal-brackets K K, eccentrics L L, fixed on a shaft Mand running in the brackets K K, upright swinging arms D D, on which theshoe I is hinged at one end, and flexible separator-s traps attached attheir ends to the arms D D, respectively, above and below the shoe I,and running around bearings therefor on the shoe I near its otherextremity, substantially as dscribed.

4. A flexible vibrating grain-separator and strzuv-conveyer, the ends ofwhich are secured adjustably at a distance apart to swinging arms, andbearings on which the separator is supported medially movably, theadjustment of the ends of the separator being respectively toward orfrom the pivotal point of the swinging arms, whereby a variable throw ofthe separator may be obtained, substantially as described.

5. In a grain-separator, a pair of swinging arms pivoted at one end 011a common axlerod, and a shaking-shoe hinged to the arms medially andextending at or nearly at right angles therefrom, in combination with aflexible separator and conveyer secured at its ends to the swingingarms, and supported medially movably at a distance from the swingingarms on bearings therefor on the shoe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN M. SAILER.
